UNITED STATES FIDELIUS'TSCHOFEN, OF VIENNA, AUSTRIA-HUNGARY.

MAGIC PICTURE.

SPECIFICATION forming part of Letters Patent No. 471,305, dated March 22, 1892.

Application filed September 30, 1890. Serial No. 366,656. (No specimens.) Patented in Germany January 13,1890, No. 53,325 i in France February '7, 1890, No. 190,525 in Italy February 8, 1890, XXIII, 26,926, and L111, 26, and in England February To all whom it may concern.-

Be it known that I, FIDELIUS TSOHOFEN, of Vienna, Austria-Hungary, have invented certain new and useful Magic Pictures, (for which I have obtained Letters Patent of Germany, No. 53,325, dated January 13, 1890; of Great Britain, No. 2,130, dated February 10, 1890; of France, No. 190,525, dated February 7, 1890, and of Italy, dated February 8, 1890, No. 26,926, Vol. XXIII, and No. 26, VOLLIIL) of which the'following is a specification.

My invention relates to improvements in magic pictures and forms a novel, entertaining, and instructive game for both children and adults.

My device consists in an apparently blank piece of paper or card or other suitable mate-- rial which, on being rubbed over with colored pencils or crayons or with colored powders or the like, produces pictures or wordssuch as answers to questions-visibly printed above.

My invention is more particularly described in the following: A piece of paper, card, or other suitable material having a perfectlysmooth, preferably glazed, surface is inscribed with letters or words or pictures, preferably in outline, either drawn, written, or printed, or, in short, transferred to the said paper, card, 850., in any convenient manner. Such lines are of the same color or tint as the glazed ground crayons, powder, &c.,tl1e latter will adhere to the roughened lines, but not to the glazed surface of the card, thus bringing out the inscription or picture.

Having now particularly described and ascertained the nature of my said invention, what I claim, and desire to secure by Letters Patent, is-

The herein-described magic picture, which consists, essentially, of suitable material having a smooth ground and rough lines thereon, indicating pictures or inscriptions which are normally invisible and which are adapted to become visible by rubbing the surface with pencil, crayon, or the like, substantially as set forth.

In witness whereof I hereunto set my hand in presence of two witnesses.

FIDELIUS TSOHOFEN.
